Identifier

PLSX

Protein name

RecName: Full=Phosphate acyltransferase; EC=2.3.1.n2; AltName: Full=Acyl-ACP phosphotransacylase; AltName: Full=Acyl-[acyl-carrier-protein]--phosphate acyltransferase; AltName: Full=Phosphate-acyl-ACP acyltransferase;

Gene name

plsX

FUNCTION: Catalyzes the reversible formation of acyl-phosphate (acyl-PO(4)) from acyl-[acyl-carrier-protein] (acyl-ACP). This enzyme utilizes acyl-ACP as fatty acyl donor, but not acyl-CoA (By similarity).

CATALYTIC ACTIVITY: Acyl-[acyl-carrier-protein] + phosphate = acyl-phosphate + [acyl-carrier-protein].

PATHWAY: Lipid metabolism; phospholipid metabolism.

SUBUNIT: Homodimer. Probably interacts with PlsY (By similarity).

SUBCELLULAR LOCATION: Cytoplasm (By similarity). Note=Associated with the membrane possibly through PlsY (By similarity).

SIMILARITY: Belongs to the PlsX family.
